  • Page 119 Discharge procedure and how to cut off power to power circuit Caution DANGER Voltage of about 360V is charged at both ends of smoothing capacitor 330 µ F x 3. High voltage (DC 360V) is also charged at screw and terminal sections of system power module. During continuity check of each circuit of electrical parts in outdoor unit is performed, to prevent secondary trouble, disconnect red/gray wire connected to system power module (SPM) from diode stack.
